Jeremiah Lowin 19fdac7b02 Refactor provider execution: components own their execution (#2663) ... * Add test_custom_subclass_tasks.py * Refactor provider execution: delegate to middleware via wrapper components - Remove execution methods (call_tool, read_resource, etc.) from Provider base - Add FastMCPProvider* wrapper classes that delegate to child server middleware - Move task routing to Tool._run() using contextvars (_task_metadata, _tool_call_key) - Add convert_to_tool_result(result, output_schema) utility for Docket results - Add convert_to_prompt_result() utility for prompt task results - Pass namespaced key via add_to_docket(name=) for mounted tool lookup * Standardize add_to_docket() with fn_key/task_key parameters All components now use explicit fn_key (function lookup) and task_key (result storage) parameters instead of relying on implicit key handling. This fixes mounted component task execution where the MCP-visible key differs from the Docket-registered function name. * Add middleware chain tests for three-level mount hierarchy Tests verify middleware runs at parent, child, and grandchild levels for tools, resources, prompts, and resource templates. * WIP: Provider refactor - unified submit_to_docket, template _read() in progress Work in progress on refactoring execution to use component _read()/_run()/_render() methods. Template background tasks not yet working - needs fix for Docket key lookup. * Fix conversion functions to take full component for attribute access Pass Tool/Prompt/Resource/Template to conversion functions instead of individual attributes, ensuring access to serializer, output_schema, mime_type, etc. Also fixes mixed-content output schema validation. * Refactor: unified convert_result() methods and check_background_task helper - Add convert_result() instance methods to all component types (Tool, Prompt, Resource, ResourceTemplate) - Extract duplicated task routing logic into check_background_task() helper - Fix type annotations on FastMCPProviderResource.read() and FastMCPProviderPrompt.render() - Update protocol.py to use component.convert_result() uniformly * Update tests to use namespace= instead of deprecated prefix= parameter		2025-12-21 15:03:24 -05:00
